Smoothfollow script C# How to rotate the camera?

I'm using C# version of unity sample script of SmoothFollow. I want to rotate the camera to multiple different positions. I have only been able to rotate around the X axis so far by modifying `float wantedRotationAngle = target.eulerAngles.y;` to `float wantedRotationAngle = target.eulerAngles.y + 90;` Thanks.

         {
                 // Early out if we don't have a target
                 if (!target)
                         return;
         
                 // Calculate the current rotation angles
                 float wantedRotationAngle = target.eulerAngles.y;
                 float wantedHeight = target.position.y + height;
                 float currentRotationAngle = transform.eulerAngles.y;
                 float currentHeight = transform.position.y;
         
                 // Damp the rotation around the y-axis
                 currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
         
                 // Damp the height
                 currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);
         
                 // Convert the angle into a rotation
                 Quaternion currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);
 
                 // Set the position of the camera on the x-z plane to:
                 // distance meters behind the target
                 transform.position = target.position;
 
                 //rotate camera
                 transform.position -= currentRotation * (new Vector3 (0, 0, 1)) * distance;
             
                 // Set the height of the camera
                 transform.position = new Vector3 (transform.position.x, currentHeight, transform.position.z);
 
                 // Always look at the target
                 transform.LookAt (target);
                 
         }
